First, some important information. ECM 16197427-BJLF, Current bin and definition should be attached. Running MAP. Mask id changed to AA, cylinder volume changed to 47.87ci. Fuel pressure key on engine off approx. 28psi. Fuel pressure drops off to 0 in seconds. 7.4l throttle body with injector flow rate of 916cc/min at 14.7 psi per. Guesstimation of the fuel pump is Walbro 50psi 27lph free flow. Im trying to get the fueling in the ball park for idle so that I can zero the mechanical timing, she's spraying a whole lot of fuel at idle right now. Pressure regulator is adjustable. I guess what I think I need is a good line on the math that will enable me to calculate and set injector constants and pulse width. Any help would be appreciated. Also, when I hit enter to type this I don't get a new paragraph, so I hope it turns out easy to read.IM
